Eariler this year, Computer Music magazine had a special issue on Ableton Live 6 with an exclusive Live Pack designed by Dennis DeSantis. The issue sold out making the Live Pack difficult to come by. Good news, Ableton has made the Live Pack available for free on their web site, get it here - The Dennis DeSantis Live Pack.
The pack contains "a number of pads, electronic percussion samples and effects, all saved in easy-to-use Instrument and Effect Racks. There's also an instructional demo set that showcases many of these racks."
On a side note, Ableton has since hired DeSantis as their "Head of Documentation"
